In September 2019, the inaugural shoe collaboration between sneaker blog Highsnobiety and New Balance was introduced, thanks to the creative genius of Hikmet Sugoer. Dubbed the Highsnobiety x 577 'Ulam Spiral', this shoe draws inspiration from the iconic graphical representation of prime numbers that was born in 1963. The upper of the shoe cleverly combines a mesh base with suede and leather panels, which feature stylish perforations at the toe. The dominant color of this silhouette is an eye-catching pink, which is complemented by a blue hue at the heel and an elegant shade of grey at the toe, paying homage to New Balance's beloved Boston brand.
